//  MODULE:   winmain.c
//
//  PURPOSE:   Calls initialization functions and processes the message loop
//
//
//  PLATFORMS: Windows 95
//
//  FUNCTIONS:
//    WinMain() - calls initialization functions, processes message loop
//
//  COMMENTS:
//
//

#include <windows.h>            // required for all Windows applications
#include "globals.h"            // prototypes specific to this application

//
//  FUNCTION: WinMain(HINSTANCE, HINSTANCE, LPSTR, int)
//
//  PURPOSE: calls initialization function, processes message loop
//
//  PARAMETERS:
//
//    hInstance - The handle to the instance of this application that
//          is currently being executed.
//
//    hPrevInstance - This parameter is always NULL in Win32
//          applications.
//
//    lpCmdLine - A pointer to a null terminated string specifying the
//          command line of the application.
//
//    nCmdShow - Specifies how the main window is to be diplayed.
//
//  RETURN VALUE:
//    If the function terminates before entering the message loop,
//    return FALSE.
//    Otherwise, return the WPARAM value sent by the WM_QUIT message.
//
//
//  COMMENTS:
//
//    Windows recognizes this function by name as the initial entry point
//    for the program.  This function calls the initialization routine
//    It then executes a message retrieval and dispatch loop that is the
//    top-level control structure for the remainder of execution.  The
//    loop is terminated when a WM_QUIT  message is received, at which
//    time this function exits the application instance by returning the
//    value passed by PostQuitMessage().
//
//    If this function must abort before entering the message loop, it
//    returns the conventional value NULL.
//
